虽然笔者目前还不知道 BindableDictionary 能用在什么使用场景下，但是还是应童鞋的要求实现了 BindableDictionary。

基本使用如下:

using System.Linq;
using UnityEngine;namespace QFramework.Example
{public class BindableDictionaryExample : MonoBehaviour{private BindableDictionary<string, string> mDictionary = new BindableDictionary<string, string>();private void Start(){mDictionary.OnCountChanged.Register(count =>{print("count:" + count);}).UnRegisterWhenGameObjectDestroyed(gameObject);mDictionary.OnAdd.Register((key, value) =>{print("add:" + key + "," + value);}).UnRegisterWhenGameObjectDestroyed(gameObject);mDictionary.OnRemove.Register((key, value) =>{print("remove:" + key + "," + value);}).UnRegisterWhenGameObjectDestroyed(gameObject);mDictionary.OnReplace.Register((key, oldValue,newValue) =>{print("replace:" + key + "," + oldValue + "," + newValue);}).UnRegisterWhenGameObjectDestroyed(gameObject);mDictionary.OnClear.Register(() =>{print("clear");}).UnRegisterWhenGameObjectDestroyed(gameObject);}private string mKeyToDelete = null;private void OnGUI(){IMGUIHelper.SetDesignResolution(640,360);GUILayout.Label("Count:" + mDictionary.Count);GUILayout.BeginVertical("box");foreach (var kv in mDictionary){GUILayout.BeginHorizontal("box");GUILayout.Label($"{kv.Key},{kv.Value}");if (GUILayout.Button("-")){mKeyToDelete = kv.Key;}GUILayout.EndHorizontal();}if (GUILayout.Button("add")){var key = "key" + Random.Range(0, 100);if (!mDictionary.ContainsKey(key)){mDictionary.Add("key" + Random.Range(0,100),"value" + Random.Range(0,100));    }}if (mDictionary.Count > 0){if (GUILayout.Button("remove")){mDictionary.Remove(mDictionary.Keys.First());}if (GUILayout.Button("replace")){mDictionary[mDictionary.Keys.First()] = "replaced value" + Random.Range(0, 100);}if (GUILayout.Button("clear")){mDictionary.Clear();}}GUILayout.EndVertical();if (mKeyToDelete.IsNotNullAndEmpty()){mDictionary.Remove(mKeyToDelete);mKeyToDelete = null;}}}
}

运行结果如下:

输出结果如下:
